Description

La présente invention a pour objet une vanne de modulation par mélange, à sa sortie, de plusieurs flux gazeux de fluide issus de conduits différents.The present invention relates to a modulation valve by mixing, at its outlet, several gaseous flows of fluid from different conduits.

Ce type de vanne peut avoir des applications très diverses en utilisant différents fluides, et peut, notamment, être adapté sur des générateurs d'air chaud, sur lesquels elle module la puissance en adaptant, pour un débit de sortie fixé , la température de l'air aux besoins du local.This type of valve can have very diverse applications using different fluids, and can, in particular, be adapted on hot air generators, on which it modulates the power by adapting, for a fixed output flow, the temperature of l air to local needs.

De façon plus spécifique, la vanne de modulation, conforme à l'invention, est du type comportant une partie fixe et une partie mobile permettant de réguler les flux. Divers travaux ont été effectués sur des vannes de modulation, lesquelles comportent, dans certains cas, deux parties mobiles, obturant chacune un orifice d'admission de flui de (en général de l'air) ,qui fonctionnent simultanément et en sens inverse. Ces dispositifs nécessitent donc une commande mobile sur cha­que flux et une liaison mécanique permettant d'actionner et de coordonner le déplacement des deux parties mobiles. Aussi ces vannes n'offrent pas une compacité et une fiabilité suf­fisante, et nécessitent la présence d'une chambre de mélange. Dans le cas de générateurs mixtes eau chaude sanitaire-air chaud, la modulation est généralement obtenue par deux volets directionnels qui obturent plus ou moins les circuits de chauffage d'air autour d'un accumulateur de chaleur. Des pro­blèmes se posent lorsque l'on veut réguler, de façon progres­sive, le débit des fluides dans des proportions souhaitées.More specifically, the modulation valve, according to the invention, is of the type comprising a fixed part and a movable part making it possible to regulate the flows. Various works have been carried out on modulation valves, which comprise, in certain cases, two movable parts, each blocking a fluid inlet orifice (generally air), which operate simultaneously and in opposite directions. These devices therefore require a mobile control on each flow and a mechanical connection making it possible to actuate and coordinate the movement of the two mobile parts. Also these valves do not offer sufficient compactness and reliability, and require the presence of a mixing chamber. In the case of mixed domestic hot water-hot air generators, the modulation is generally obtained by two directional flaps which more or less block the air heating circuits around a heat accumulator. Problems arise when one wants to regulate, gradually, the flow of fluids in desired proportions.

L'invention a pour objet de résoudre les diffi­cultés sus-mentionnées.The object of the invention is to solve the above-mentioned difficulties.

A cet effet, conformément à l'invention, ladite partie fixe comporte, au moins, deux familles d'orifices dont chacune est reliée au conduit de fluide correspondant, et ladite partie mobile peut obturer ou découvrir plus ou moins au moins l'un des orifices d'une des familles de la­dite partie fixe tandis qu'elle découvre ou obture parallè­lement au moins l'un des orifices de l'autre desdites familles. De cette façon, un mélange progressif des flux des différents fluides est assuré dans les proportions souhai­tées. En outre, cette conception de la vanne peut lui per­mettre d'être l'organe de commande d'une chaîne de régulation.To this end, in accordance with the invention, said fixed part comprises, at least, two families of orifices, each of which is connected to the corresponding fluid conduit, and said movable part can block or uncover more or less at least one of the orifices of one of the families of said fixed part while it uncovers or blocks at least one of the orifices of the other of said families in parallel. In this way, a progressive mixing of the flows of the various fluids is ensured in the desired proportions. In addition, this design of the valve can allow it to be the control member of a control chain.

Selon une autre caractéristique de l'invention, ladite partie mobile se déplace au moins en partie dans un plan de manoeuvre sensiblement parallèle au plan d'ouver­ture et de fermeture de certains, au moins, des orifices de la partie fixe. Cette disposition permet une mise en oeuvre et un montage particulièrement aisés. En outre, les pièces sont facilement usinables et l'encombrement de la vanne réduit.According to another characteristic of the invention, said movable part moves at least partially in an operating plane substantially parallel to the opening and closing plane of some, at least, of the orifices of the fixed part. This arrangement allows a particularly easy implementation and assembly. In addition, the parts are easily machinable and the size of the valve reduced.

Avantageusement, la vanne de modulation peut être adaptée sur une installation de climatisation par air pulsé. Elle assure la modulation progressive de la puissance de l'installation. Ce type de régulation permet de limiter les problèmes de stratification des températures dans les pièces, de diminuer le différentiel dynamique de la tempé­rature ambiante, et de réduire la fréquence des montées et des descentes en température du local à chauffer et de mieux récupérer les apports gratuits et internes dudit local.Advantageously, the modulation valve can be adapted to a forced air conditioning installation. It provides progressive modulation of the power of the installation. This type of regulation makes it possible to limit the problems of stratification of the temperatures in the rooms, to decrease the dynamic differential of the ambient temperature, and to reduce the frequency of ascent and descent in temperature of the room to be heated and to better recover the free intakes. and interns of said premises.

L'invention s'applique également à un procédé d'utilisation d'une telle vanne de modulation, dans lequel lorsque l'on découvre une partie au moins de la surface des orifices d'une famille, pour libérer progressivement le débit de l'un des flux, on obture simultanément une partie au moins de la surface des orifices de l'autre famille, pour diminuer progressviement le débit de l'autre flux. De cette façon, on peut obtenir un débit de sortie constant, et une courbe, présentant la proportion des flux mélangés en fonction de l'ouverture et de la forme des orifices, sen­siblement linéaire.The invention also applies to a method of using such a modulation valve, in which when at least part of the surface of the orifices of a family is discovered, to progressively release the flow of the one of the flows, at least part of the surface of the orifices of the other family is simultaneously closed, in order to progressively decrease the flow rate of the other flow. In this way, it is possible to obtain a constant output flow, and a curve, presenting the proportion of the mixed flows as a function of the opening and the shape of the orifices, substantially linear.

En se reportant tout d'abord à la figure 1, la vanne, repérée dans son ensemble 1, comporte essentiellement une partie fixe 2 dans laquelle sont ménagées, au moins, deux familles d'orifices 5, 6 et une partie mobile 3 pouvant obtu­rer ou découvrir plus ou moins au moins l'un des orifices d'une des familles 5, 6 de la partie fixe 2 alors que simul­tanément elle découvre ou obture, plus ou moins, au moins l'un des orifices de l'autre des familles 5, 6. Chaque famil­le d'orifices 5, 6 de la partie fixe est reliée en aval de la vanne à un conduit (non représenté) d'admisson séparée des fluides. La surface totale des familles d'orifices 5, 6 contrôlant chacun des flux est équivalente pour chaque famille. La partie fixe 2 se présente sous la forme générale d'une plaque dont la partie centrale, de forme sensiblement cylindriqueue, est évidée. Les orifices de la famille 5 sont ménagés dans le fond de l'évidement, et se présentent, dans cet exemple, sous la forme de quatre secteurs d'un disque. Les orifices de la famille 6, au nombre de quatre sont ménagés dans les parois inclinées de l'évidement et ont en projection une forme sensiblement rectangulaire.Referring first to Figure 1, the valve, identified as a whole 1, essentially comprises a fixed part 2 in which are formed, at least, two families of orifices 5, 6 and a movable part 3 capable of closing off or discover more or less at least one of the orifices of one of the families 5, 6 of the fixed part 2 while simultaneously it discovers or blocks, more or less, at least one of the orifices of the other of the families 5, 6. Each family of orifices 5, 6 of the fixed part is connected downstream of the valve to a conduit (not shown) for separate intake of the fluids. The total area of the families of orifices 5, 6 controlling each of the flows is equivalent for each family. The fixed part 2 is in the general form of a plate, the central part, of substantially cylindrical shape, is hollowed out. The orifices of family 5 are formed in the bottom of the recess, and are, in this example, in the form of four sectors of a disc. The orifices of family 6, four in number, are formed in the inclined walls of the recess and have in projection a substantially rectangular shape.

La partie mobile 3 qui se déplace, au moins en partie,dans un plan de manoeuvre 9, sensiblement parallèle au plan d'ouverture et de fermeture de la famille d'orifices 5 de la partie fixe 2, se présente, dans l'exemple illustré, sous la forme de quatre secteurs 4 d'un disque, entraîné en rotation autour d'un axe central 10, dont chaque partie extrême 11 est inclinée par rapport au plan de manoeuvre 9 du disque. La partie 12, située dans le plan de manoeuvre 9 du disque, et la partie extrême 11 constituant les secteurs 4, sont disposées respectivement en regard des familles d'orifices 5 et 6, de la partie fixe 2.The mobile part 3 which moves, at least in part, in an operating plane 9, substantially parallel to the opening and closing plane of the family of orifices 5 of the fixed part 2, is shown, in the example illustrated, in the form of four sectors 4 of a disc, driven in rotation about a central axis 10, each end portion 11 of which is inclined relative to the operating plane 9 of the disc. The part 12, located in the operating plane 9 of the disc, and the end part 11 constituting the sectors 4, are arranged respectively opposite the families of orifices 5 and 6, of the fixed part 2.

La figure 3 présente une autre forme de réalisa­tion de la vanne dans laquelle la partie fixe 2 comporte une première famille d'orifices 5 qui se présente sous la forme d'un orifice circulaire central et une seconde famille d'orifices 6 qui se présente sous la forme de quatre quarts de cercle d'une surface équivalente à celle de l'ori­fice central 5.FIG. 3 shows another embodiment of the valve in which the fixed part 2 comprises a first family of orifices 5 which is in the form of a central circular orifice and a second family of orifices 6 which is in the form of the shape of four quarter circles with an area equivalent to that of the central opening 5.

On note que la partie mobile 3 est constituée par deux plaques 7, 8 coplanaires. Le déplacement des deux plaques 7, 8 est assuré simultanément et éventuellement symétriquement par exemple par une vis à pas inversé (non représentée) qui leur permet de coulisser l'une par rap­port à l'autre en s'écartant de leur axe de jonction 13. Les deux plaques sont constituées notamment par un matériau isolant (non représenté) de façon que l orsqu'elles obturent complètement l'une des familles d'orifices, elles assurent l'isolation thermique. Les deux plaques 7, 8 se déplacent dans un plan de manoeuvre 9 sensiblement paral­lèle au plan d'ouverture et de fermeture des deux familles d'orifices 5, 6 de la partie fixe 2.Note that the movable part 3 is constituted by two plates 7, 8 coplanar. The displacement of the two plates 7, 8 is ensured simultaneously and possibly symmetrically for example by an inverted pitch screw (not shown) which allows them to slide relative to each other away from their junction axis 13 The two plates consist in particular of an insulating material (not shown) so that when they completely block one of the families of orifices, they provide thermal insulation. The two plates 7, 8 move in an operating plane 9 substantially parallel to the opening and closing plane of the two families of orifices 5, 6 of the fixed part 2.

Un mode de réalisation possible de la vanne selon l'invention est présenté à la figure 4. On note que la partie fixe 2, est une plaque dans laquelle sont ménagées une famille d'orifices 5 se présentant sous la forme de quatre secteurs de disques, et une famille d'orifices 6, au nombre de quatre, en forme de part de secteurs de disque, interca­lés entre les orifices 5 à l'extérieur de ceux-ci et de surface totale équivalente. On peut aussi noter que la par­tie mobile 3 est constituée par quatre secteurs 4 d'un dis­que qui se déplacent dans un plan de manoeuvre 9 sensible­ment parallèle au plan d'ouverture et de fermeture des orifices 5, 6 de la partie fixe 2. La partie mobile 3 est entraînée en rotation autour d'un axe central 6 par un moteur (non représenté) fixé sur l'axe.A possible embodiment of the valve according to the invention is presented in FIG. 4. It is noted that the fixed part 2 is a plate in which a family of orifices 5 are formed, being in the form of four sectors of discs , and a family of orifices 6, four in number, in the form of a portion of disc sectors, interposed between the orifices 5 outside of them and of equivalent total area. It can also be noted that the mobile part 3 is formed by four sectors 4 of a disc which move in an operating plane 9 substantially parallel to the opening and closing plane of the orifices 5, 6 of the fixed part 2. The mobile part 3 is rotated about a central axis 6 by a motor (not shown) fixed on the axis.

En se référant à la figure 5, on voit que la vanne peut être adaptée sur une installation de climatisa­tion à air pulsé du type comportant un corps de chauffe ou échangeur de chaleur 14 autour duquel circule un fluide chaud 15, une paroi isolante 16 entourant le fluide chaud 15 et une enceinte d'isolation externe 17 entre lesquelles circule un fluide froid 18. Les deux flux 15, 18 s'écoulent entre une admission 19 disposée en amont de l'accumulateur 14 et une évacuation 20 disposée en aval de celui-ci comportant un aspirateur-ventilateur schématisé en 21. Les caractéris­tiques amont et aval sont repérées en référence à l'écoule­ment des flux, tel que représenté par les flèches à la figure 5.Referring to FIG. 5, it can be seen that the valve can be adapted to a forced air conditioning installation of the type comprising a heating body or heat exchanger 14 around which circulates a hot fluid 15, an insulating wall 16 surrounding the hot fluid 15 and an external isolation enclosure 17 between which a cold fluid circulates 18. The two flows 15, 18 flow between an inlet 19 disposed upstream of the accumulator 14 and an outlet 20 disposed downstream of it Ci comprising a vacuum-ventilator shown schematically at 21. The upstream and downstream characteristics are identified with reference to the flow of flows, as represented by the arrows in FIG. 5.

On note que l'on obtient en amont de la vanne un mélange de fluides à température variable suivant le débit de fluide chaud s'écoulant à travers l'orifice 5 et le débit de fluide froid s'écoulant à travers l'orifice 6.It is noted that a mixture of fluids at variable temperature is obtained upstream of the valve according to the flow of hot fluid flowing through the orifice 5 and the flow of cold fluid flowing through the orifice 6.

La vanne de modulation 1 permet donc de réaliser une modulation en température par mélange en sortie de celle-­ci de deux flux thermiques l'un chaud, l'autre froid. Entraî­née par un moteur à deux sens de rotation (non représenté), la vanne peut être commandée par un régulateur du type pro­portionnel intégral dérivé et assurer, de ce fait, la modu­lation de la puissance de l'installation en fonction des besoins du local à chauffer. En fonctionnement "été" elle assure la fermeture de l'orifice 5 et évite ainsi le tirage parasite autour du corps de chauffe 14.The modulation valve 1 therefore makes it possible to carry out temperature modulation by mixing, at the outlet thereof, two thermal flows, one hot, the other cold. Driven by a motor with two directions of rotation (not shown), the valve can be controlled by a regulator of the derivative integral proportional type and thus ensure the modulation of the power of the installation according to the needs of the room to be heat. In "summer" operation, it closes the orifice 5 and thus prevents parasitic draft around the heating body 14.

Revenant aux figures 1 à 4, on voit que la partie mobile 3 peut découvrir ou obturer complètement tous les orifices desdites familles 5, 6 de la partie fixe 2. En particulier, lorsque la partie mobile 3, qui se déplace au voisinage des différents orifices de la partie fixe 2, découvre une partie au moins de la surface des orifices d'une famille 5, pour libérer progressivement le débit de l'un des flux, elle obture simultanément une partie, au moins de la surface des orifices de l'autre famille 6, pour diminuer progressivement le débit de l'autre flux. La partie mobile 3 peut être arrêtée dans toutes les positions intermé­diaires (entre l'ouverture et la fermeture complète) de façon à moduler à volonté le débit des flux. La vanne 1 effectue donc à sa sortie, et simultanément, le mélange et la régulation des deux flux. Il n'est pas nécessaire de prévoir de chambre de mélange particulière. De plus, sa structure en matériau isolant lui permet d'assurer la fonc­tion d'obturateur thermique.Returning to FIGS. 1 to 4, it can be seen that the mobile part 3 can uncover or completely block all the orifices of said families 5, 6 of the fixed part 2. In particular, when the mobile part 3, which moves in the vicinity of the different orifices of the fixed part 2, uncovers at least part of the surface of the orifices of a family 5, to progressively release the flow of one of the flows, it simultaneously closes part, at least of the surface of the orifices of the other family 6, for gradually decreasing the flow rate of the other flow. The mobile part 3 can be stopped in all the intermediate positions (between opening and complete closure) so as to modulate the flow rate at will. The valve 1 therefore performs at its outlet, and simultaneously, the mixing and regulation of the two flows. No special mixing chamber is required. In addition, its structure in insulating material allows it to perform the function of thermal shutter.

Diverses variantes peuvent être apportées aux modes de réalisation illustrés et décrits. On peut, notam­ment, prévoir différents systèmes d'entraînement des pla­ques de la partie mobile présentée à la figure 3. Leur dé­placement peut être assuré par un ensemble pignon-crémail­lère. Un moteur d'entraînement, dont l'axe est perpendi­culaire au plan de manoeuvre des plaques, peut aussi permet­tre leur déplacement dans un mouvement d'un quart de tour.Various variants can be made to the embodiments illustrated and described. It is possible, in particular, to provide different drive systems for the plates of the movable part shown in FIG. 3. Their displacement can be ensured by a pinion-rack assembly. A drive motor, whose axis is perpendicular to the plane of operation of the plates, can also allow their displacement in a movement of a quarter turn.

En outre, la paroi de l'évidement central de la partie fixe 2, telle que présentée à la figure 1, peut être réalisée en forme de tronc de cône, à pente plus ou moins prononcée. L'angle d'inclinaison de la partie extrême 11 des différents secteurs de la partie mobile 3 étant alors adapté à l'angle du tronc de cône, afin que celle-­ci se déplace au voisinage des orifices ménagés dans la paroi.In addition, the wall of the central recess of the fixed part 2, as shown in FIG. 1, can be made in the form of a truncated cone, with a more or less pronounced slope. The angle of inclination of the end part 11 of the different sectors of the mobile part 3 is then adapted to the angle of the truncated cone, so that the latter moves in the vicinity of the orifices provided in the wall.

Enfin, on notera que si les pertes de charge des conduits d'admission, reliés aux familles d'orifices 5, 6 , sont équivalentes, la proportion de mélange des flux de fluides varie sensiblement linéairement avec le pourcentage d'ouverture des orifices.Finally, it will be noted that if the pressure losses of the intake ducts, connected to the families of orifices 5, 6, are equivalent, the proportion of mixing of the fluid flows varies substantially linearly with the percentage of opening of the orifices.

Cependant, si l'on adapte en les modifiant la forme de trous de la famille 6 ou de la famille 5, la pro­portion de fluides mélangés en fonction du pourcentage d'ouverture des orifices ne varie plus linéairement ; on peut adapter cette forme en fonction de la loi non linéaire que l'on souhaite obtenir et qui traduit une réponse voulue et déterminée de la vanne.However, if the shape of family 6 or family 5 holes is adapted by modifying them, the proportion of fluids mixed as a function of the opening percentage of the orifices no longer varies linearly; we can adapt this shape according to the nonlinear law that we want to obtain and which translates a desired and determined response of the valve.
